These are the best fitting goggles I have ever worn.  I bought them for swimming laps, 1/2 mile twice a week, as cross training for trail running.  I love the fit of these goggles and the adjustable straps.  They do not loosen like other goggles I''ve worn.  They fit my face perfectly.  They do tend to fog up after many uses around a quarter mile.  The quick spit anti fog stuff works pretty well for that.

piece of junk.  Broke within 10 minutes of getting into the water.  The side clip broke and disappeared into the water.  The goggles are useless.

couldn't get a good seal. Better for larger face.

I use these goggles for everyday swim practice in the indoor pool.  They can be used very easily outdoors but I don't swim outdoors unless I'm doing a triathlon.  For triathlons, I prefer to use clear plastic goggles.  I like these TYR Femme Crystalflex goggles because they have a bigger eye piece and so they don't press so severely onto my eye sockets.  They rarely leak and if they do there's a good reason.  Otherwise, I have no complaints about this product.

I swim several times per week and I was looking for something that wouldn't leave lines under my eyes two hours later.  After reading a good review about these goggles I bought a pair the next day.  Huge disappointment.  Bright red marks on upper and lower eyes and very deep lines under eyes.   I've been swimming for years and these are the worst I seen for leaving goggle lines.   They are very easy to adjust and don't leak.

I was hoping these goggles would help avoid raccoon eyes after swimming.  The dent marks are in a different spot but they're still there.
